To all whom a may comm; 1

-Be' it known that LCGIiORGE JQKELLER MAN, a citizen of the IInitedStates of- America, and a resident of'Chicago, county of Cook, and Stateof Illinois, have invented a new and usefullmprovementinMachinesforForming Sausage Patties, of which the following is a specification.-

The purpose of this invention is to provide a machine for-forming anddelivering sausage pattles ln'conditlon for packaging without thenecessity ofhaving any of the meat directly handled" during the formingor feeding operation, and for deliveryjof the patties on asheetof paperso thatthe machine ofthe fluid content of the patties during forming-anddelivering operation and to provide means for preventing the substanceoperated' 'upon from adhering to the forming dies and delivery plungersThe preferred embodiment of theinvention is shown in thedrawings,in"which'- Figure 1 is a plan view of the machine.

Fig. -5 is asectional view taken on the line fr gm 1 Figs. 6 and 7are-sectional details of the forming dies.-

The construction shown is in the form for .an attachment tovchopped'meat feedingideand comprises a horn shaped conduit termi-,nating -in a plurality of 'pattie aforming -molds and provided withmeans whereby Ithepressureof the meat in the horncmayber controlledduring andafter thiefpassage. of

horn and operating the delivery plungers.

The delivery plungers are made hollow in order to permit thecirculationof warm water 'thereithrough. .f This circulation of warmwater serves to keep the mechanism at the required temperatureand also.pre-

vents the "meatand liquidtherein from be- T ing chilled on and, adheringto the metal Suitable viceis provided for sealing the dischargeapertures of the forming molds during the filling operation. I a I Inthe drawings, the construction as above outlined comprises a horn 1which at the receiving end 2 isthreaded for attachment to-any suitable"means for delivering the chopped meat' under pressure to the horn. Thishornis stiffened by a web?) to prevent "the machine' from sagging due toits weight and the downward force e'xerted thereon through the,operating lever 4. This lever, of course, maybe operated by mechanicalpower but as herein shown is'a'handle suitable for manual operation. Thelever 4 is arranged to oscillate around thesupporting shaft 5 but passesthrough a yoke -6,"fas't to the shaft 5, but allowing a preliminary free5 return motion ofthe lever 4 before the shaft is' oscillated in orderto i first interrupt the pressure of the chopped meat in the horn 1after the form ing receptacles 7 have been filled and during operationof the delivery plungers 15. For this purpose the rear end of operatinglever 4 is connected by a link Qlto a valve operat- I ing arm 10;Thevalve 11 operated by the arm 10 is located in the passageway 12 ofthe horn 1. n This passagewayat the delivery end branches into aplurality of divisions 13 (Fig. 1) each leading to a pattie formingopening-7 in a mold 14. The forming openings? in'themoldare preferablyelliptical in plan, in order to produce patties of'this form, Theseopenings are formed in a transversely extending rigid casting 14, whichmaybe integral with the horn" 1," and extend vertically through thecasting, providing ways for the vertically reciprocating plungers or Idies 15. The latter are hollow, as indicated'in Figs. 5,:6-and 7-, linorder to provide for the circulation of a warming fluid. Each is securedto and communicates with a cross head or manifold 16, also hollow toprovide for the circulation ofea liquid-through the dies. The crosshead16 is providedwith a pair of upwardly extending posts 17 (Fig. 52)passing through arms 18 secured to posts 19. The lattera-re carried-by avertically-- movable table 20 normally urged down-wa rd by springs 21.with a wear plate 22 hearing against a cam 23 carried by the shaft .5.Whenthisishaftis rocked to the left (Fig. 4), the cam 23 senvesito firstrapidly. lift' the. table-.QO-and thento hold. itfirmly againstthe lower.sur- ,face 24: of .the casting 14. The upper. surfaceofthe table 20carries a -resilient.mat 25. for sealing ,the discharge apertures ofmold, 14-.

The-armsJS carried bythe posts 19, upon theupward: motion oftableQO,first idly slide alongathe' posts- 17 before 'en-gaging'the nuts 26along the posts. and lift the latter, together with thecrosshead 16anddies 15 carriedthereby. 7

Before these dies fully uncover the ports 27 of passageways 13, the;table 20 comes into contact with the lower surface Qlfof (lasting 14..Thedies 15? are then pushed furthen upward-ibyithe pressure of. thesubstance fedinto themolds.

Thedownward'limit of-Fmovement of table 20 andtheparts carriedthereby i determined by the settingfofi-screws 3.2,,Fig. 2. These screws ooact witlihexagonalbushings 3.3 on the cross head16; and which bushings serve}: for connection with flexible-conduits"through. which the; warming fl l dfor the dies; passes; Theupward i of:theoperatingrhandle 4 is determined by $121 55 Stop '34,. 3, :but the.shaft 51' is sti freeeto mtatetri the: right-under; the. ae-
